A basic horizontal barchart type visualiation is shown - as a screenshot from a Just Giving email. The number on the left lower end of the bar is £180 the number on the right, the upper end of the bar is £500. The bar gauge is shown exactly halfway between £180 and £500, implying that £180 is half of £500. £250 is half of £500, so this is really deceptive UX although being used for a good motivational cause.

While I appreciate the motivational data visualisation @justgiving.bsky.social the implied sum in this visualisation is driving me wild!
